My Girlfriend locked herself out of her Nissan truck up at the carnival. The keys are in the ignition and her purse is on the seat. It's 9 at night and the cops won't help. She's on her way over, I imagine I can just push the latch in with my trusty putty knife on her sliding back window. Is this easy? Sorry if this is sort of a criminal question but I couldn't find much searching the web and she'll be here in a minute. I don't think we have any 24 hour locksmiths. Thanks Josh
